本文研究了时谐SH波载荷作用下嵌入均匀夹杂物的弹性矩阵中位移场的评估。我们认为圆柱形夹杂物与周围无限大基体之间的结合在圆周方向上是部分损伤的。夹杂物和基体的材料被建模为均匀的，各向同性的，和线性弹性。本文介绍了一种描述SH波在含部分损伤粘结夹杂物中散射的解析方法。随后，一个数值例子来说明的方法，它可以扩展到SV/P波的散射在一个简单的方式。
This work addresses the evaluation of the displacement field in an elastic matrix due to the presence of an embedded homogeneous inclusion under time-harmonic SH-wave loads. We consider the bond between the circular cylindrical inclusion and the surrounding matrix of infinite extent to be partly damaged in the circumferential direction. The material of both inclusion and matrix is modelled as homogeneous, isotropic, and linearly elastic. An analytical approach is introduced here for describing the scattering of SH-waves by inclusions with partly damaged bond. Subsequently, a numerical example serves to illustrate the methodology, which can be extended to the scattering of SV/P-waves in a straightforward manner.
